Abstract: 1486366 Desalting sea water SOC ITALIANA RESINE SIR SpA 22 July 1975 [10 Sept 1974] 30608/75 Heading B1B A process for desalting sea water, in which hot sea water is passed through an evaporation zone, vapour is condensed on an indirect heat-exchange surface and the resulting distillate is recovered, comprises recovering a portion of the brine not evaporated, admixing this portion with replenishment sea water, supplying the mixture as cooling fluid for the heat-exchange surface thereby pre-heating the mixture, and further heating the mixture in a head heater before passing the resulting hot sea water into the evaporation zone, and is characterised by:-acidifying the replenishment sea water to a pH of 3.5 to 4.5 by addition of a mineral acid, - submitting the acidified water to a turbulent state followed by steam treatment to remove the major part of the volatile impurities, - adding an alkali metal sulphite in an amount of 10 to 20 times the weight of residual oxygen and in such amount that the residual sulphite after reaction is from 1000 to 4000 parts per billion (10<SP>12</SP>), - admixing the thus treated replenishment sea water with the recycle brine portion and supplying the mixture as cooling fluid before passing it into the head heater, and - adding to the hot sea water issuing from the head heater, before passing it into the evaporation zone, an alkali metal hydroxide to maintain the pH at 8.

Abstract: 742,164. Welding by fusion. MOND NICKEL CO., Ltd. Nov. 18, 1953 [Nov. 19, 1952], No. 32016/53. Class 83 (4). [Also in Group XI] In gas-shielded arc welding of nickel and nickel alloys, especially those comprising 60-70 per cent nickel and 20-30 per cent copper, a stream of inert gas, e.g. helium or argon, is passed axially around the electrode and an annular laminar stream of hydrogen is directed to converge inwardly upon and envelop the inert gas stream. The inert gas is supplied from tube 36 in the handle 4 of a torch to flow through passages 38, 41 and emerge as a non-turbulent stream through a nozzle 26, having a cylindrical inner surface and a conical outer surface, arranged about a non-consumable electrode 3. Hydrogen is supplied through a tube 46 in the handle to flow down a passage 48 to an annular passage 50 and through a series of ports 51 to a reservoir 52, formed in part by a cavity in the end of the nozzle 26, where its flow is reversed and then directed down a passage 35 between the outer surface of nozzle 26 and a nozzle 32. The nozzle outlets are coplanar. The angle of the passage 35 to the axis of the electrode may be 10-30 degrees. Cooling of the torch is effected by passing water through an annular passage 20 and a current supply stud 18 is water-cooled. A sleeve 55 extends from the nozzle 32 and is spaced from the body to reduce water vapour condensation. Specification 649,888 is referred to.

Title: Scanning radar antenna beam position indicator
IPC: G01S13/91
Filed: 1952-12-17
Abstract: 723,511. Pulse radar. BENDIX AVIATION CORPORATION. Dec. 17, 1952 [Dec. 28, 1951], No. 32030/52. Class 40 (7). In a pulsed radar system in which beam sweeping is effected by periodically varying the relative phase energization of individual ones of an array of radiators deflection of the ray of a cathode-ray tube indicator in accordance with the sweeping of the beam is controlled by means of a voltage derived by phase comparison of the energy from a predetermined point of variable phase in the array with the energy from the source which supplies the array. As shown in Fig. 1, a waveguide 11 (coupled to a conventional T-R radar system, not shown) supplies energy to a variable-width waveguide 12 which is driven by a motor 10 to vary the relative phasing of individual dipoles 13 to effect beam sweeping. In accordance with the invention a portion of the input energy in waveguide 11 and a further portion at a selected point in variable-width waveguide 12 is " tapped-off " by means of directional couplers 14 and supplied to individual mixers 15 (one path including a phase shifter 17 to establish a desired initial phase relationship) in which the " tapped-off " signal energy is converted to a suitable intermediate frequency by mixing with the output of a local oscillator 16. The outputs from mixers 15 are then fed, via limiter amplifiers 18, to a phase detector 19 and Fig. 2 (not shown), which produces an output signal the peak value and polarity of which depends on the degree of " in-phase or 180 degrees " out-of-phase " relationship between the input signals. The output from phase detector 19 is then supplied to a circuit 21 (described as a Differential Action circuit) which comprises (as shown in Fig. 3) a transformer 37 to the secondary winding of which the output from 19 is fed and to the primary winding of which a pulse from the transmitter pulse-modulator is supplied, the circuit operating to charge condenser 43 to a potential representative of the amplitude of the output signal from 19 during the occurrence of each pulse from the pulse-modulator. The voltage across condenser 43 is then employed to control the sweep generator 22 so that the ray of the cathode-ray indicator tube 23, to a control electrode of which received echo signals are applied, is swept across the screen of the tube in recurring paths starting from a common origin, the angular orientation of the paths varying with the voltage across condenser 43.
